Small egg from normal layer. What’s up?

[Gilmoregirls]

My gals have been lying normal size eggs since September. Good layers, all of them! But today I got this tiny egg. Girls are 8 mos old and have been laying since July. This is kind of odd. Should I be concerned about it? Normal lifestyle - no new changes. Coop, run and feed are the same. Not sure what’s going on. I believe it’s from one of my Brown Comets. Thank you!

It's completely normal!
It's called a fairy or fart egg, it happens.

An occasional fairy egg is nothing to worry about.
